Do Peta Murgatroyd and Brant Daugherty have an announcement to make? An eyewitness tells Us Weekly that the former Dancing With the Stars partners were making out at the Trevor Live L.A. event in Hollywood on Sunday, Dec. 8.

The 28-year-old Pretty Little Liars actor and 27-year-old professional dancer sat together at a table in the back of the ballroom inside the Hollywood Palladium. According to a fellow partygoer, the twosome were inseparable all night and were showing PDA throughout the event. While the lights were dimmed for Glee's Amber Riley performance, Murgatroyd was rubbing Daugherty's back and they shared kiss. The insider tells Us they later kissed again several times during the charity's raffle.

The next day, Daugherty posted a photo on Instagram of the two posing together at the event. "Had so much fun at Trevor Live last night with this lovely lady by my side," he captioned the shot. In the sweet snapshot, Daugherty and Murgatroyd share a hug while smiling for the camera.

In an interview with Celebuzz in November, the ABC Family actor laughed off rumors that he was dating his DWTS partner. "For the one millionth time, no we are not dating," he said. "We are locked in a studio with a camera crew for five hours every single day. It's not a place where something like that can really grow. We are very close though, we're very comfortable around each other. I don't think we'd be able to do our jobs well if we weren't."
